color bleeding

[mervin_lim23]

i know there's alot of c&c's about these images. i have attached some of the images i made. i posted them in other forums and one told me there are color bleeding going on on the images. how will i improve correct color bleeding? can anyone help me with this isuue? i also notice that there are splotched ang light leak but i checked the model and all the joints and connection are all snapped together but still there are leaks. maybe there are some adjustments to be made in the render setup. another thing i like the images to be very sharp.how will i adjust it to be vey sharp?where to adjust? first bounce is IR and LC in my second bounce. LC value is 1000. color mapping is reinhard. filter is adaptice QMC/catmul rom.i set my IR to High.

 

 

thanks in advance

for a sharper render - use fixed for IS, catmull rom for AA

as for color bleeding - you can use VrayOverridematl for the wall. Adjusting it will simultaneously lessen light leaks

thank you ronel... actually i havent use vray overidematerial before. i'll research on it thnks. i'll use fixed on IS i'll try it ryt away...

i have a tutorial about VrayMatlOveride... its getting Rid of Color Bleeding. Hope i can post it here. Its so long time since my last visit... i will just browse around and find a place to post it here.

 

by the way nice render you have here

thanks arch ronel for appreciating.... another problem of this image is glass balance and until now im doing all the tweaking to make that glass perfect.

regarding light leaks, what are other causes for aside from geometry connections? thanks in advance

[Thablanch]

For the light leak, check: check sample visibility in your Irr map Rollout. If the geometry is 99% tight, this should take care of the rest.

 

For the Color bleed, there is a saturation value, in the global illum. parameters.

ok i'll check sample visibility... coz i doubled check the geometry and its tight..

and regarding saturation, right now its in default value (1.0) what value should i put? thanks in advance

If you put the saturation at 0, it means "no" color bleed, ( for the Irr pass, that is) It will also looks a little unnatural, as the color bleed is part of the advantages of GI, I would say try different values.. until you are satisfied

thanks it has alittle improvement considering your saturation value. thanks alot
